which may be used either by themselves as buttons, nail-heads, etc., orinlaid or worked into tilesor plates such as are' used infloorcoverings, wall-coverings, mosaics and the like. The inventionconsists in the novel way of working plastic materials such as are usedin the manufacture of artificial stones.

The object ofthe invention is to produce.

from diilerently colored plastic materials used in artificialstone-making, decorative disks, slabs, tiles and plateswhichmay becovering floors, walls, inlaid furniture and the like, in a new, simple,easy, and cheap way, where no stencils, forms, molds or such like areused, and by which beautiful and effective designs or patterns can beproduced; J 3

The new process is carried out as follows I l 'Difierently coloredplastic materials such as are used in the manufacture of, artificialstone are taken. From masses of this differently colored lastic materialthin sheets and also suitably sized sticks are formed llwo or moreofdifierent color may then be rolled in and around one another as shownin Figure 1. According to another arrangement one or more sheets (ofdiflerent colors when a plurality are used) are rolled around one ormore colored sticks as shown in Figs. 2 and 3.

The cylindrical bodies so obtained are out,

e ther alone or combined with one another; into disks or slabs.

Further, several cylindrical bodies produced by rolling difl'erentlycolored sheets into one .another or around a plastic stick may bearranged side by side around a central core consisting of one or severalplastic sticks (which may, if desired, have been previously wrappedaround. with, or rolled like or rosaceous design.

show the design of a rose.

into, one or more sheets) in such a waythat the central core issurrounded on its whole circumference by such cylindrical bodies asshown inFig. 4. The bundle obtained in this way is rolled with gentlepressure until the cylindrical bodies which form the bundle combine intoanother larger cylindrical body as shown in Fig. 5. Such body when outperpendicularly to its axis thereby forming disks shows on the surfaceof the cut a flower If this larger cylindrical body,obtained by theabove described operations, is again wrapped around with, or rolledinto, one or several plastic diflerently colored sheets and then cutinto disks, the flower-like design appears on the surface'of the diskssurrounded by one or several differently colored rings.

lln'addition to those described other designs can, of course, beproducedas, for

example, the design of a rose as shown in Fig- 6. Here two diiierentlycolored sheets of plastic material are first rolled into one viouslyrolled into a sheet and afterward pressed substantially fiat or curved)are arranged so that they partly cover one another.

The body so obtained after having been wrapped around with, or rolledinto, one or several sheets, is cut, perpendicularly to its axis, intodisks or slabs which on the surface Of course several of the bundlesproduced in the above described way may be. combined and united invarious ways and by cutting these united bundles into a number of disksor slabs and placing the same in a large with carpetlike design as shownfor example in Fig. 7. i

Having thus described this invention what is claimed and desired tosecure' by Letters Patentis:

1. A process of producing decorative slabs of plastic'materials, whichconsists in rolling together several colored plastic masses to producedifferently colored plastic sticks and slab of plastic material we canobtain slabs substantially cylindrical body, and finally cutting saidcylindrical body perpendicularly to its axis, into slabs.

, 2. A process of producing decorative slabs of plastic materials, whichconsists in arranging a plurality of plastic sticks comprising aplurality of'difi'erent colors, wrapped with a plastic sheet of adifi'erentcolor from said sticks, side by side around a plastic central,core until this core is surrounded by said sticks, rolling the bundle soobtained with gentle pressure until the several sticks are; united intoa cylindrical body, Wrapping said cylindrical body with a colored sheetof plastic material, and finally cutting the body so obtainedperpendicularly to its axis, into slabs.

- 3., A process of producing decorative slabs of plastic materials,which consists in assembling differently colored pieces with one anotherto produce a stick, then arranging around the stick so obtained, andserving as a core, a plurality of plastic sticks which have each beenpreviously wrapped With a plastic sheet, such sticks being placed aroundthe core'in such a way that each of said plurality of sticks covers aportion of the said core, then gently pressing the bundle so ob-.

tained, and finall cutting the body so obtained perpendicu arly to'itsaxis, into slabs. 4. A process of producing decorative slabs -5. Aprocess of producing decorative slabs of plastic materials, whichconsists in producing plastic sticks each Wra ped previously with adifi'erent colored s eet, placing these sticks side by side around aplastic core until this core is surrounded by such sticks, wrapping thebundle so obtained with a plastic sheet and then rolling the productuntil it becomes cylindrical, cutting this cylindrical body into slabs,and finally placing a plurality of the slabs so obtained into softplastic. material, thereby producing.

plates having desired designs.

In testimony whereof I afiix' my signature in presence of two witnesses.
